WILLIAM B. CHISOLM, OF CHARLESTON, SOUTH CAROLINA.

MACHINE FOR MIXING FERTILIZERS.

SPECIFICATION forming part of Letters Patent No. 311,291, dated January27, 1885.

Application filed July 11, 1884.

To all whom it may concern.-

Be it known that 1, WILLIAM B. OHIsoLM, of Charleston, in the county ofCharleston and State of South Carolina, have invented a new and ImprovedMixing-Machine, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved apparatusfor mixing phosphates, cement, ores, clay, 820., either wet or dry.

The invention consists in the construction and arrangement of parts, aswill be hereinafier described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my improvedmixing-machine. Fig. 2 is an end elevation of the same. Fig. 3 is across-sectional elevation of the same.

A drum, box, or trough, A, made of wood or metal, and either square orcircular in crosssection, is provided with an opening, B, in the middleof its bottom, which opening can be closed by a plug, C, secured to oneend of a pivoted lever, D. the opposite end of which carries a weight,D, for holding the plug C in the opening B. In the ends E of the box ashaft, F, is journaled, which passes longitudibelt-pulleys G and Gmounted on one end.

On the shaft F a series of arms, H, are mounted, the arms being arrangedalternately at right angles to each other, and the planes of the armsbeing at angles of forty-five de- On the arms H blades or Wings J areheld, which are flared toward their outer ends. The wings or blades Jare each provided with a longitudinal slot, K. through which bolts M arepassed, which also pass through the arms H, whereby the blades or wingsJ can be adtheir outer ends will be a greater or less distance from theshaft. If the ends of the wings or blades wear off, the wings or bladescan be adjusted to take up the wear, and so that the ends of the wingswill always be close to (No model.)

they carry the material from the ends of the box or trough to the middleand to the discharge-opening B. The wings J and their arms are providedwith flanges a along the edges, so that the said wings or blades willact as scoops.

The materials to be mixed are passed into the box or trough at the ends,and are carried to the middle of the trough, and are thoroughly mixedand agitated. When the material is mixed sufficiently, the plug C isopened and the material permitted to drop through the opening B.

I am aware that it is not broadly new in mixing-cylinders to provide theblades with slotted extensions and bolts for adjusting them a greater orless distance from the cylinder, and I do not claim such as of myinvention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with a trough or box, ofashaftjournaled longitudinally in the same, arms formed on the shaft,and blades or wings held adjustably on the arms, the said blades orwings being inclined from the ends toward the middle of the box,substantially as herein shown and described.

2. The combination, with the box or trough A, of the shaft F, the arms Hon the same, the wings or blades J, having flanges a and slots K, and ofthe bolts M, substantially as herein shown and described.

I 3. The combination, with the box or trough A, having a centralopening, B, of the shaft F, the blades or wings J, held on the same,which blades are inclined from the ends to- .ward the center, and oftheplug C, held on
